It has heretofore been known to provide separate door locking meanswherein the locking bolt was key controlled from both sides of a door,and the .latch member was arranged for manual operation from one side ofthe door only. Such an arrangement, however, had the disadvantage thatwhile a locked and latched door or an unlocked and latched door could beopened from one side, there was no way to permit entrance from the otherside of the door, even though the party rightfully possessed a key. Thelatch would prevent opening the door from the other side.

The present invention proposes to retain the augmented security obtainedby utilizing both a latch member and locking bolt, and provide theimprovement which will permit through the use of a single key controlledmeans a normal locking and unlocking operation of the locking bolt fromeither side of a door, and also additionally permit the further use ofthe key controlled means, after actuating the locking bolt to anunlocked position, to effect movement of the latch member to anunlatched position.

In US. Pat. No. 2,989,859 it was known to utilize a single keycontrolled means for actuating a plurality of locking boltssimultaneously to locked and unlocked positions, but such concept madeuse of the movement of one bolt, which was actuated directly by the keycontrolled means, to actuate the second bolt which was operativelycoupled to it. This arrangement, it will be noted, did not envision theconcept of utilizing the single key controlled means for selectivelyactuating the locking components. The present invention thereforeconstitutes an improvement over this patent and provides features andadvantages as will be more fully pointed out herein.

SUMMARY OF THE INVENTION The present invention relates generally tolocks, and is more particularly concerned with a combination locking andlatching assembly for narrow stile door frames, in which provision ismade for selective operation of the locking bolt and latching memberfrom a single key controlled means.

Although the present invention is described and claimed in connectionwith lock mechanisms and latching mechanisms finding particularlyadvantageous use with narrow stile doors, the invention is likewiseapplicable to other doors, where space is not a limitation. It istherefore contemplated that the invention shall not be limited solely touse on narrow stile doors.

It is one object of the herein described invention to provide a uniquecombination of locking and latching mechanisms which provide a greaterdegree of security, yet permit the selective operation of the lockingand latching members by means of key controlled means.

A further object is to provide in the foregoing combination means foractuating the locking bolt in a normal manner independently of theposition of the latch operable by means of a handle which is connectedwith the locking mechanism through a lost motion connection.

Another object is to provide in a combination locking mechanism andlatching mechanism according to the present invention, a unique mountingfor the latching member which permits easy accommodation for lockassemblies having different back-sets.

Still another object is to provide in connection with the latchingmember, improved releasable detent means whereby the latch member may bereleasably retained in a non-latching position.

Further objects of the invention will be brought out in the followingpart of the specification, wherein detailed description is for thepurpose of fully disclosing the invention without placing limitationsthereon.

FIG. 5 is a fragmentary sectional view taken through the latchingmember, substantially on line 55 of FIG. 2.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring more specifically tothe drawings, for illustrative purposes there is disclosed in FIG. 1 acasing which is designated generally by he numeral 10. This casingcomprises generally a pair of side plates 11 and 12 which are secured inspaced apart relation by conventional spacing pins or other means, andincluding a face plate 13 which may be removably attached as by suitablescrews 14 at the forward edges of the side plates. This face plate isformed with adjacent rectangular slots or openings 15a and 15b withinwhich a bolt structure'16 and latch structure 17, respectively, are

- movable to retracted and extended positions, as will member, andactuation of the latch member independently of the locking boltposition.

A still further object is to provide a unique combination lockingmechanism and latching mechanism in which a latch member of the latchingmechanism is retracted positions, a pivot pin 23 being positionedbetween the bolt ends, this pin having its opposite ends supported inthe side plates 1 l and 12 respectively.

The configurations of the inner ends of the bolt plate members areperhaps best shown in FIGS. 2 and 3. The innermost end of the centralplate is terminated at the pivot pin 23 in an angularly extending endedge 24, as shown in dotted lines, beyond which extends the adjacentends of the outer plates, thus forming a space therebetween. Theadjacent ends of the outermost plates on each side thus have overlappingend portions which receive the pivot pin 23 therethrough and support thebolt for pivotal rotation. These outer plates also provide lobe portions25-25, which are in each case formed with a Y-slot 26 having dwellpositions at its ends as indicated by the numerals 27, 28 and 29 for apurpose which will hereinafter be explained in detail.

The bolt 16 is actuated between its retracted and extended positions bymeans of an actuating lever 30 supported for swinging movement on apivot 31 at one end, this pivot being vertically positioned with respectto the pivot pin 33 of the bolt 16. The other end of the actuating leverextends into the previously mentioned space at the inner end of the boltand carries a transversely extending pin 32 having its ends respectivelypositioned on opposite sides of the lever and respectively positioned inthe adjacent Y-slots 26-26 of the bolt structure. As thus arranged, thelever 30 is constrained to limited singing movement between the forwardand rear edges of the side plates 1 l and 12.

Provision is made for positively releasably locking the bolt 16 in itsretracted position and its extended position. This is accomplished bydetent means associated with the lever 30, which includes a cylindricaldetent 33. This detent is provided with a circumferentially extendinggroove (not shown) intermediate its ends which forms a portion ofreduced diameter, this portion being slidable in a slot 34 in theactuating lever. As shown in FIGS. 2 and 3, this slot is constructedwith an enlarged end portion 35 to facilitate mounting the detent in itsoperative position. The outermost ends of the detent 33 are,respectively positioned for movement in arcuate slots 36 respectivelyformed in the side plates 11 and 12. The slot 36 has dwell notches 37and 38 at its ends. The detent is biased in an upward direction in theslot 34 by a coiled spring 39 placed on each side of the actuating lever30, one end of the coil spring being secured to an anchor pin 40 carriedby the lever, and the other end of the spring bearing against and seatedin a circumferential groove (not shown) formed in the detent. As thusarranged, the detent will be biased into the dwell notch 37 in theextended position of the bolt 16, and into the dwell notch 38 in theretracted position of the bolt, as respectively shown in FIGS. 2 and 3.In the dwell positions of the detent 33, the detent assumes a positionbetween transversely extending spaced abutment pins 41 and 42, as shownin FIGS. 2 and3 respectively.

Various mechanisms may be utilized for motivating swinging movement ofthe lever 30, and with the lock structure disclosed herein, provision ismade for actuating the lever from either side of the casing. Forpurposes of illustration, a lock cylinder 43 of conventional typeoperable by a key is mounted in an opening 44, such an opening beingformed in each of the side plates 1 1 and 12 for the accommodation ofthe lock cylinder. The lock cylinder carries rotatably mounted means 45having a cam extension 46. The rotatably mounted means 45 is controlledby a key by means of which the cam extension may be rotated through 360in opposite directions from a key insertion and removal position. Itwill also be observed that the center of rotation of the rotatablymounted means 45 is vertically aligned with the center of rotation ofthe actuating arm pivot 31, but ofi-set relatively thereto.

Advantage is taken of the path of movement of the cam extension 46 withrespect to the movement of the abutment pins 41 and 42, which enablesthe utilization of the cam extension to serve the dual purpose ofreleasing the detent 33 and thereafter shift the actuating arm from oneof its locked positions to the other so as to motivate the bolt 16 fromone position tothe other. As shown in FIG. 2, the detent is positionedin the dwell notch 37 and the pin 32 is positioned in the dwell position27 of the Y-slot of the bolt. In this position, the bolt 16 ispositively locked in its extended position. Should it be desired to movethe bolt to its.

retracted position, the cam extension 46 would be rotated in acounterclockwise direction from the key insertion and removal position,which in this case is when the extension is extended vertically upward.Upon movement. of the cam extension to the position shown in FIG. 2, itwill be observed that the abutment pins 41 and 42 are in such a positionthat the outermost end of the cam extension will pass the abutment pin41 and move into engagement with the detent 33. Continued movement ofthe cam extension will cause it to force the detent from the dwell notch37 and to a position which permits the extension end to pass between theabutment pins 41 and 42. As the cam extension comes in contact with theabutment pin 42, the applied forces will now shift the actuating arm 30to the position shown in FIG. '3. In this position, the bolt 16 will bein a retracted position, and the pin 32 will be in the dwell position 28of the Y-slot. In this position of the arm, the detent 33 will be biasedinto the dwell notch 38, as the cam extension is continued in itscounterclockwise movement. In this position of the actuating arm, itwill be observed that the abutment pin 42 has assumed a position whichwill permit the end of the cam extension to pass by this abutment pinand be continued in its movement to the key insertion and removalposition. The action of the lock elements will be similar to that justdescribed except in reverse order, when rotating the cam extension fromthe key insertion and removal position in a clockwise direction. Duringactuation of the bolt between its retracted and extended positions, thepin 32 will move into dwell position 29 of the Y-slot at theintermediate position of the bolt. Moreover, the curvature of the Y-slotis such that the pin 32 will act to restrain free movement of the boltin going from an extended position to retracted position.

From the foregoing description, it is believed that it will be evidentthat the key cannot be removed and inserted at a position which wouldleave the bolt in other than a fully extended locking position or afully retracted unlocked position.

As will be seen from the drawings, the latch structure 17 is positionedbelow the bolt structure 16, and as shown, comprises a generallyL-shaped supporting bracket 50 which is positioned between the sideplates 11 and 12, this bracket having one leg 51 positioned at the backofthe casing and attached at its ends by means of lateral sideprojections 52 which extend into openings 53 formed in the side plates.The other leg of the bracket, as indicated at 54, extends toward thefront of the casing and is provided at its end with depending side lugs5555 provided with openings for receiving a retaining pin 56 having itsends respectively supported in the side walls of the casing. The flatsurface of the leg 54 provides a supporting surface upon which the latchstructure is slidably supported for reciprocable movements betweenretracted and extended positions.

As shown in FIG. 5, the latch structure assembly includes a latch pin orstem 57v which has a tubular end portion 58 supported by coining orotherwise mounting in an opening of a connected guide plate 59 havingside projections 60 arranged to extend into an associated guide slot 61in the associated side plates of the casing. A compression spring 62 ismounted with one end seated in thecylindrical end portion 58, and itsother end anchored as indicated at 63 to the leg 51 of the bracket 50.This spring normally urges the latch pin or stem 57 towards the front ofthe casing so that the latch structure will be normally in an extendedlatching position.

The latch structure may assume'various forms, but is shown as comprisingin this case an inner body 64, preferably of a suitable metal, which isadapted to slip over the outer end of the stem 57 to which it may besecured by means of a suitable set screw, as indicated at 65.

Surrounding the body is an outer shroud 66 formed of a suitable plasticto provide parallel side walls and a rounded outer end, as indicated at67. The side walls are provided with elongate guide grooves, as shown at68, which are adapted to receive a pin 69 mounted in the respective sideplates of the casing. This pin and groove arrangement stabilizes thereciprocable movement of the latch member. As a protective measure, thetop and bottom surfaces of the shroud are provided with a metal topplate70a and metal bottom plate 70b. These plates are coextensive with theupper and lower surfaces of the shroud and provide a protectiveshielding therefor.

Provision is made for manually moving the latch from an extended orlatching position by providing an actuating handle, as generallyindicated at 71, in FIG. 1. This handle has an elongate grip portion 72and a hub portion 73 which is provided with a square shaft 74 adapted tobe operatively positioned within a rotatably mounted latch lever bearing75, the opposite ends of this bearing being rotatably supported independing extensions of the side plates 11 and 12 of the casing. Thearrangement just described permits the handle 71 to be selectivelymounted on either side of the door structure, depending upon the type ofoperation required at the particular installation.

The latch lever bearing provides a support for a latch lever in which apair of spaced lever arms 76 and 77 are secured to a cylindrical hub 78which is rotatably mounted on the bearing 75. The outermost ends of thelever arms 76 and 77 are positioned on opposite sides of the cylindricalend portion 58 and in front of the guide plate 59 in such a manner thatrotation of the lever arms in a counterclockwise direction, as viewedcarried by the latch lever bearing 75 is movable between spacedshoulders which form abutments 81 and82 at the ends of the recess 79.

Provision is made for actuating the latching mechanism by the keycontrolled means, when the lock mechanism is in an unlocked position.For such purpose, there is provided at the back side of the casing aslide plate 83 which is mounted for endwise guided movement. At itsupper end, this plate has on each side a hook element 84 which isslidingly engaged with a guide pin 85 carried by the adjacent side plateof the casing. At its lower end, the slide plate is provided on eachside with a lug 86 which is connected by a pivot pin 87 to the adjacentlever arm as positioned on its side of the casing.

bar portion 91. A spring 92 normally urges the hinge extension in aclockwise direction, as viewed in FIGS. 2 and 3.

- In the locked position of the bolt 16, as shown in FIG. 2, it will beobserved that spring 62 urges the latch 17 towards its extendedposition, and acts through the lever arms 76, 77 to move the slide platein an upward direction. It will also be observed that in this positionthe bridging bar 91 of the hinge extension is engaged by the adjacentedge of the actuating lever 30 and will be moved in a counterclockwisedirection so that the outer fingers 90 will be positioned out of thepath of travel of the cam extension 46, thus permitting the camextension to perform its normal operation of motivating the lockmechanism so as to move bolt 16 to an unlocked position, as shown inFIG. 3.

In the unlocked position, the actuating lever 30 is moved away from thehinge extension 88 so that the hinge extension can now move under theaction of spring 92 in a clockwise direction in order to position thefingers 9090 in the path of travel of the cam extension 46, during itscounterclockwise rotation subsequent to its having actuated the bolt 16to an unlocked or retracted position. Further rotation of the rotatablemeans 45 will cause the slide plate to move downwardly and actuate thelatch 17 to a retracted position. This actuation is independent of thelatch handle operation by virtue of the lost motion connection betweenit and the lever arms 76, 77.

Provision is also made for releasably retaining the latch member inretracted position, when desired. For this purpose, there is provided awire detent 93 which is mounted for sliding movement below the metalbottom plate 70b of the latch structure, the bottom plate containing arecess opening 94, as shown in P16. 5, which is adapted to receive theend of the-wire-detent when the latch is in retracted position. Movementof the detent is accomplished by providing a deflected portion 95 at itslowermost end, this portion being engageable through an opening 96 inthe face plate below the latch element, as shown in FIG. 1.

Another feature of the disclosed invention resides in the adaptabilityof the latching mechanism for installations wherein the back-set mayvary. For casing structures having different back-sets, the distance, asindicated at a in FIG. 2, between the center of rotation of therotatable means 45, and the back edge of the side plate of the casing,is maintained at a constant value. Thus, to accommodate for thedifferent back-sets, it is only necessary to change the length of thelatch or stem pin 57 to adapt the latch mechanism for the differentback-sets.

From the foregoing description, it is believed that it will beappreciated that the lock and latch structure described accomplishes thestipulated objects set out for the invention.

Various modifications may suggest themselves to those skilled in the artwithout departing from the spirit of our invention, and hence, we do notwish to be restricted to the specific form shown or uses mentioned,except to the extent indicated.
